Here's a very slightly used USB Dual Tube Pre, in like new condition.
I got the bug to try some digital recording and signal processing, got the interface and software to try it, then as I usually do with electronic accessories and effects, used it just enough to see how it worked then never did anything else with it.
It's got at most an hour's use on it and looks brand new, though the box is a little rough, but was that way when I bought it new from GC a few months ago. It sounds very warm and smooth and I particularly like the opto compressor and HPF. It comes with everything included when new.
$80 shipped (to continental US only)
